and useful Improvements in Aseptic Appliances, of which the following is a specification.

The present invention relates to aseptic appliances for surgical and .medical uses, and its object is to provide means for 0btaining access to inner portions of the human body by the passages leading thereto, such as to the uterus through the vagina or to the bladder through the urethra, and at the same time avoiding the transference of germs to said interior parts from the exterior of the body, or to upper parts of said passages from lower parts thereof.

In the accompanying drawing, Figure 1 is a perspective view of a bacteria shield; Fig. 2 is a similar view of a pusher tube enlarged; Fig. 3 is a view similar to Fig. 1 of said members assembled; Fig. 1 is a similar view of the same parts inverted and in a different position; Fig. 5 is a detail view of a modified form of glass tube; Fig. 6 is an enlarged sectional view showing a further modification of the invention; Fig. 7 is a view on a smaller scale of said modification in its final position.

Referring to the drawing, 1 indicates a thick sheet of soft rubber or other suitable material of size suflicient to cover the vulva, and, when ,desired, the perineum, thighs, and lower abdomen. Around a. suitably sized hole in said sheet is secured an open end of a tube 2 of thin soft rubber or other suitable material, of size sufficient to line the passage, and either open or closed at the unattached end, as may be desired.

4 indicates a tube of rigid, preferably transparent, material, as glass, one end of which is closed except for a narrow elongated opening 5. In the modification of the invention shown in Fig. 5 said opening is narrowed by means of claws or projections 9 which extend into the opening. The end having the larger opening is threaded on the outside and is screwed into a handle 6 of two or three inches in length.

Before using, the apparatus is sterilized and the tube 2 is drawn through the narrow opening 5 in the end of the tube 4, and the whole apparatus is placed in a sterile covering.

In use the sheet 1 is placed in contact with the exterior parts which it is intended .to cover, and the glass pusher tube l is pushed inward into the passage. Thereby the tube 2 is unfolded and inverted, passing through the transverse opening 5, so that what was the inner wall of the tube 2 now comes in contact with the wall of the pas sage. The pusher tube 4 is then withdrawn, if in the vagina, but remains in the urethra, the handle being removed and a rubber tube attached. It will now be seen that the passage is lined with an aseptic lining, which extends on the outside. over the adjacent parts.

The object of narrowing the opening 5 in the inner end of the pusher tube is that the rubber tube, when passing therethrpugh, may be completely closed against the entrance thereinto of any bacteria-laden material from the passages themselves or from other parts of the system. The tube remains closed at its passage through the transverse opening 5 during the whole of the unfolding of said tube.

In the modification of the invention shown in Figs. 6 and 7 there is used, in addition to the tube 2 attached to the sheet 1, an inner tube 7 of thin soft rubber of about the same diameter and length as the outer tube 2. These tubes when placed one within the other are rolled together on a rolling pin, of hard rubber or other suitable material, to form a ring, and when the ring has been formed the free end of the inner tube 7 is tied with, string. 8 indicates a glass tube of size varying with the passage, and having a handle attached thereto.

The ring formed as above described, is placed in the external orifice of the passage, and the tube 8 is pushed between the tubes 2 and 7, so as to unroll the ring up the passage, the inner tube 7 passing into the tube 8. It is then withdrawn with the latter,

'leaving the outer tube as an aseptic lining for the passage.

For the sake of brevity and convenience of nomenclature, the word rubber in the claims will be considered to include any flexible impervious material.

I claim 1. An aseptic means for lining the walls of a passage in the human body comprising an aseptic sheet of comparatively thick rubber having a hole therethrough of approximately the same diameter as the passage when undergoing normal distention, and an aseptic thin rubber tube one end of which is connected to said sheet around said hole and the other end is open for the passage therethrough of an instrument, medicament, or the like.

2. An aseptic means for lining the walls of a passage in the human body comprising an aseptic sheet of comparatively thick rubher, the edge of which is free throughout its entire circumference and having a hole therethrough of approximately the same diameter as the passage when undergoing normal distention, and an aseptic thin rubber tube one end of which is connected to said sheet around said hole, and the other end is open for the passage therethrough of an instrument, medicament or the like. 3. An aseptic appliance comprising an aseptic sheet of comparatively thick rubber having a hole therethrough, an aseptic thin rubber tube one end of which is secured to said sheet around said hole, and an aseptic rigid tube, one end of which is closed except for an elongated narrow aperture therethrough, said rubber tube extending through said aperture and within said rigid tube.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
